IMPROVEMENT IN THRASHERS AND SEPARATORS.

Specification forming part of Letters Patent No. 38,379, dated May 5, 1863.

To all whom it may concern.-

Be it known that we, W. W. DINGEE and A. B. FARQUIIAR, of York, in the county of York and State of Pennsylvania, have invented a new and useful Improvement in the grainseparator patented by Peter Geiser October, 1852, and October 9, 1855, an improvement on which was patented by the said W. W. Dingee and A. B. Farquhar June 17, 1862; and we do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side elevation of the separator.

Fig. 2 is a reversible coupling.

A, Fig. l, is a portion of the line-shafting connecting the power and separator. B is a continuation of this line-shafting, driving the rake-shaft O by means of the bevel-gearing D.

The advantages of driving the rake-shaft by the line-shafting are that the number of revolutions of these two shafts is nearly equal, an the wear and liability to break of gearing E, which drives the cylinder, is much less than when the power required to drive the rake-shaft is taken from the cylinder.

F is the hopper of the fan, placed immediately in front of the front axle of the wagon the wheel G of which is turned against the sill H, and is out of the way in measuring the grain. This arrangement is more convenient than when the hopper is placed behind the hind wheels, as is customary.

J is the feeders platform, hinged to the sills oftheseparatoratpointK. BrakeLissituated above the wheels and is connected to the feet.- ers platform by rod M, and is applied by a man putting his weight on the feeders platform J. It is held from the wheels, when not required, by hook N.

Fig. 2 is a coupling to connect the line'shafting of the power and separator. The squat e ends of shafts A A slip loosely in the coupling, and are not secured to it in any way to prevent a longitudinal movement therein.

0 is a universal joint, which admits of an angle in the coupling. This coupling is lia ble to wear, but not being secured to the lineshafting, it may be reversed, which will add very much to its durability. Having it loose also admits of sufficient longitudinal movement in the line-shafting to accommodate any displacement of the power caused-by the strain of the horses.

What we claim as our invention, and desire to secure by Letters Patent, is-

l. Driving the rake-shaft G from the continuation B of line shaft A.

2. Placing the delivery-hopper F of the fan in front of the front axle of the wagon.

3. The combination of the feeders platform J with wagon-brake L.

4:. Connecting the line-shafting by reversible couplings in which the shaft has a free longitudinal movement.
